Eco-Friendly Paint Thinner

People use paint thinners for different purposes.

They are crafted to yield similar results as conventional paint thinner.

Benefits of Eco-Friendly Paint Thinners and Solvents

While shortlisting the best eco-friendly paint thinners from the list above, you may be thinking if it is really that important to use them.

Well, eco-friendly thinners aren’t just a marketing gimmick for companies to show that people are opting for a better solution.

They are indeed safer for humans and the planet.

Here are some benefits of using eco-friendly paint thinners:

1- They are extremely safe

While using toxic paint thinners, humans get exposed to a lot of chemicals that can damage their internal organs and cause skin allergies.

Eco-friendly paint thinners use organic and natural compounds to yield similar results.

2- They lower pollution emission

The major reason to go for eco-friendly paint thinners is the safety of the environment.

Since they do not use or emit any dangerous chemicals, you can avoid harming the planet and ozone deterioration.

3- They are all-purpose and can be used for various tasks

Usually, the organic non-toxic paint thinners are made with citrus oils that can be used for various different purposes.

It doesn’t just thin paint but also cleans the paint off brushes, de-waxes, and removes epoxy resins, gums, and tars.

Even if you don’t plan to use the paint thinner for painting purposes too frequently, keeping them in your basement can be useful in many other areas.

By using eco-friendly paint thinners, you not only just do a favor to your environment but also prioritize your health and safety.

These reasons should be sufficient to convince you about using eco-friendly paint thinner.

Are there any disadvantages?

The only drawback of using these household paint thinner substitutes is they can extend the drying time of the paints.

So, if you plan to work on a piece of furniture you want to use in a week or so, it’s not very good to use these options.

It’s therefore good to use other products like turps, turpentine, naphtha, acetone, and mineral spirits.

If you want, you can also try oils like sunflower oil, refined walnut oil, and linseed oil that can work.

Can You Simply Use Water or Make a Homemade Paint Thinner?

Water is one of the best natural ways to thin water-based latex paints or clean paintbrushes.

You can use it safely when you do not want to use paint thinners.

You just need to take the latex paint in a bucket and add water (or isopropyl alcohol).

Add 200ml of water to every 4L of paint to achieve the best results.

Stir it thoroughly with a paint stirrer or a wooden stick. Slowly add more water if needed to get the right consistency.

The only problem with adding water to paint is you can use it only when you are working with water-based paints like latex or acrylic paints.

You cannot use it for thinning (or washing) oil-based paints.

This is where natural homemade paint thinners can be used.

Preparing homemade paint thinner is straightforward as you can simply mix lemon oil and linseed oil in a ratio of 1:6.

Stir the mixture thoroughly and use it as a substitute to paint thinners when you are working with oil-based paints.

Vinegar, baby oil, sunflower, or vegetable oil can also be used for thinning oil-based paints if you don’t have lemon oil and linseed oil.

Few Precautionary Tips to Keep In Mind

While eco-friendly paint thinner alternatives work very well, these may be hard to clean tough paints after they are dried on the surface.

So, if you need to deal with dried paints, it’s good to use commercial paint solvents that are chemical-based.

A few other things you may need to keep in mind when working with paint thinners include:

  • If working with lacquer-based paints, it’s better to use lacquer thinner
  • Never put dried paint and/or thinner into a microwave oven to thin it
  • Do not try to thin oil paint with gasoline indoors; it can be really hazardous
  • When working with chemicals, always use a proper respirator rated for organic vapors
  • Never pour the paint solvents down the sink drain or into a nearby street gutter
  • Always use proper measuring cups or 1/2 gallon-gallon container made of appropriate materials for measuring
  • Chemical-based paint thinners and solvents can be highly flammable; never use them near flames or high heat

Final Thoughts

Working with chemical-based paint thinners, solvents, and fumes can be very hazardous to your health.

It can even pollute our environment to a great extent upon disposal.

The universal benefits of Eco-friendly paint thinners make them a worthy investment for a lot of projects that may include removing grease, waxes, resins, tar, or thinning paints.

Though you will have to pay a little more for eco-friendly products, the advantages outweigh the price.

You can use paint thinners for several purposes, so you don’t have to purchase them for one thing and never bring them to use again.

My favorite least-toxic paint thinners from the above list include Bioshield Citrus Thinner.

Since the product is manufactured from Citrus oil, it’s completely natural. Also, it fulfills all your paint thinning needs.

The good thing is you don’t have to wear your protective gear while using these solvents.

IMO, you should not use any chemical-based paint thinners, especially if you paint more often.

Going for an all-natural alternative will help you in accomplishing the projects without any health risks involved.
